Synthesis and Biological Activities of Organotin Schiff Base Complexes
ISBN: 9783659560644 / Angielski / Miękka / 2014 / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. 2-Thiophenecarboxylic acid hydrazide has been treated with benzaldehyde in 1:1 molar ratio at room temperature in the presence of a suitable solvent to yield Schiff base. Then it has been treated with R2SnCl2/R3SnCl in 1:1 molar ratio to synthesize organotin(IV) complexes under reflux conditions. Organotin(IV) complexes have been characterized by FT-IR and semi-empirical study. FT-IR data explains the tetrahedral arrangement of sulphur donor ligand with tin metal which is further confirmed by semi-empirical study. Least value of dipole moment of complex 3 explain the trans orientation of...

Negotiating Turns: Bapsi Sidhwa's Fiction About Parsi Life
ISBN: 9783659129261 / Angielski / Miękka / 2012 / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. It is quite natural for a writer to give room to his own culture and social background in ones writings. Bapsi too is not an exception. Being a Parsi by birth, she is profoundly rooted in her own Parsi culture and beliefs and completely engrossed in it. Bapsi has given voice to all that happened to her in and outside her home.Her own life becomes the representation of the Parsi minority girls and women later on. The atmosphere at home was very much like found in Asian houses.

Clinicopathology of Newcastle Disease in Arsenic Intoxicated Broilers
ISBN: 9783659504754 / Angielski / Miękka / 2014 / 156 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This manuscript provides information about clincio-pathology in arsenic intoxicated broiler chicks and were challenged with Newcastle Disease. This information is useful in places where arsenic is higher in ground water than permissible limits and especially poultry is reared. Information generated in this manuscript can also be applied on other species present as natural habitant in the vicinity or coming to the site where arsenic is a problem. Under such circumstances, if birds are exposed to Newcastle Disease, one can realize what type of clinico-pathology occurs in such birds.

Production and Characterization of Xylanse from Aspergillus Niger
ISBN: 9783659596797 / Angielski / Miękka / 2014 / 196 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Xylanase enzymes are group of enzymes that can degrade Xylan present in plants. Xylan lignin and cellulose formed a complex matrix in plants. Lignin imparts colour to cellulose and thus eventually imparts colour to paper and pulp. Xylanase facilitates the removal of lignin from the paper pulp thus improves the brightness of paper. Xylanase was produced by Aspergillus niger using different carbon sources. UV irradiation of Aspergillus niger slightly improves the Xylanase activity than native Aspergillus niger. Twenty minutes exposure of Aspergillus niger to UV irradiation was considered...

Biological study of Schiff Base Metal Complexes derived from Drugs
ISBN: 9783659459467 / Angielski / Miękka / 2014 / 200 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The work presented concerns the preparation, characterization and biological evaluation of Cu(II) and Zn(II) complexes of Schiff bases derived from amoxycillin, cephalexin, sulphamethoxazole and trimethoprim, and salicylalde-hyde and pyridoxal. In these complexes an amino group available in the drug substances was allowed to react with salicylaldehyde and pyridoxal hydrochloride, separately, to obtain Schiff bases which were, subsequently, reacted with Cu(CH3COO)2. H2O and/or Zn(CH3COO)2.2H2O to form Schiff base metal complexes. The ligands and the complexes were characterized by...

Synthesis and Biological Activities of Sn and Pd Complexes
ISBN: 9783659607028 / Angielski / Miękka / 2014 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Tin(IV) and Pd(II) complexes are useful as antibacterial, antiviral, antifungal and antilarvicidal agents. Tin(IV) and Pd(II) complexes are also important as catalyst, water repellent, antifouling agents in paint industry and as fire retardants. Present work focus on the synthesis of tin and palladium complexes, their characterization and biological activity with respect to various fungi and bacteria. Twelve novel triorganotin(IV) complexes have been synthesized by reacting 4-Aminophenol with R3SnCl in (1:1) L/M molar ratio. In the first step ligand was being reacted with R3SnCl in anhydrous...
